Multi-User Diversity vs. Accurate Channel Feedback for MIMO Broadcast Channels
— A multiple transmit antenna, single receive antenna (per receiver) downlink channel with limited channel feedback is considered. Given a constraint on the total system-wide cha...

Stability of the Multiple-Access Channel Under Maximum Broadcast Loads
We investigate deterministic broadcasting on multiple-access channels in the framework of adversarial queuing. A protocol is stable when the number of packets stays bounded, and it...
